Mount;- 70 V In carryingout theinvention, thereis proed centrally in the bar lt'is 'a vertieal 'clamp-' vided abase member consistingof a 'subs'taning screw 17 equipped with a head 18 at its tially'oblong block 1 having a longit'udinal O e E d W a h dle 19 atuits PP slot2 extending approximately from end to end, thisclamping screw being so disposed A end thereof and provided with lateral feet that when it is turned home it will firmly 575 or lugs 3 through which fastening devices clamp the cornersot thejoint membersupon may be inserted to securethe device upon the the: arm 5 and efl'eotually hold them against corner of a workbench, indicated at 4. At vertical separation; It will be noteduthf t the'front end of the block 1, there is formed a the beam 14 is slotted in only one end por forwardly projecting overhanging arm 5 tion and'thatthe distance between the clamp- '80 through t'he' front end of. which issecured a ing screw 17 and one aw 9is fixed; The work transverse guide rod 6'and parallel, with said for which this vise is intended does not. call r'od' an adjusting screw. 7 isjournaled in said for a constantadjustment of the jaws to vary- 7 arm. The screw 7 has a blank portion at its ing material and it is not'necessary that the I j center whereby it may rotate in the arm 5 screw be always exactlyin the center of the '85 without moving through the same and at work, but it is highly desirable that the jaws the opposite sides of the armit has relativebe firm and the desired firmness is attained 7 reversed threads, as shown most clearly by the construction shown. To accommodate in Fig, 1. Collars 8 are fitted tojthe screw a wider range of work, the head 18 mzly be r'e- 40 at opposite sides of the arm whereby'to aid movable and a plurality of headsbe provid- '9? i in holding the same in proper position. Slided for interchangeable "use; and the beam 14 ably: mounted upon the guide irod 6 and hav "may be'also provided in various sizes for simo- ,ing threaded. engagement with the adjustilar interchangeableuse. 1 p ing'screw. 7 are front jaws 9, the rearffaces Journaled in the front and'rear ends of the Y of which are vertical. as shown at 10, and have base 1 is an under screw 20 equipped at its 95 ledges 11 projecting rearwardly therefrom, it front end with a handle 21 and having its ini being obvious-that thejoint members are intermediate portion engaged througha slide tended to rest upon the ledges or shelves 11 22 which constitutes a nut and will be caused and bear against the vertical faces 10. The tomove'longitudinally or the base when. the

adjusting screw 7 is equipped at onelelld with screwis rotated. This slide is provided with I overhanging flanges 23 at its sides which engage the sides of the base 1 whereby to pre-. vent lateral or twisting movement of the slide and hold itto a rectilinear path, as will be understood upon reference to Fig. 4, The front end of the slide 22 is recessed at its upper corners and in the recesses are pivotally secured the shanks 24 of the rear jaws 25, these jaws having front vertical faces and having ledges or shelves 26, corresponding to the ledges or shelves ll of thefront jaws,-and disposed substantially flush with the upper surface of the arm 5 so that the rear edges of the joint members will be supported by the rear jaws. The body of the slide fits within the slot 2 of the base, as will be understood,

and itsfront end, at its lower portion, de-v fines a forwardly projecting tongue 28 on which is seated a shim 29 having" its ends projecting under the sides of the base, as shown in Fig. 4. A set screw 30 holds the shimfon the tongue, the shim preventing rocking of thefslide on the. base. I

- In use, the viseis secured to the workbench at a cornerof .the'jsame with the jaws 9 arranged approximately parallel with the re spective edges of the 'bench' "The members which are to'be secured to'form a miter joint are placed in positionfagainst the jaws 9 and the adjustingscrew 7 then actuated so asto bring the jaws into firm. engagement with the joint members and cause the jointmembers to firmly and closely abut. The under screw 20 is then actuated so as to bring the rear jaws 25': into firm engagement with the back edgesof the joint members and firmly .fclamp. them to the front jaws, the clamping screw 17 being set to hold the work to the arm 5.v The clamp nail or miter fastening is then driven into the joint members, the arm 5 .serving as an anvil to resist, the force of the blows delivered to drive the'fastening home if the clamp 'nail is to be driven across the meeting edges of the joint members. Y Most generally, however, the clampnail is driven through the edges of the oint members longir 'tudinally of the oint, and it willbe seen that thejaws do not abut but leave an ample space for the insertion ofthe clamp nail and the operation "of thedriving tool, whether the clamp nail is to be) driven through the outer orrthe inner corner- 0f the joint. When the clamp nail is driven through the outer corner,

the inner jaws serve asan anvil, and when the clamp' na l is driven through the inner cor- :ner, the outer jaws serve as an anvil.

t will be readily onoted that 1 have pro :vided an exceedingly simple and compact vise which may be easily set to secure the members ofa joint and easily manipulated to quickly release the same after the joint hasbeen tightened. It isto be particularly noted thatthe vertical faces of the cooperating jaws aredisposed at an angle of fortyfive degrees to the longitudinal li e of the base so that they are at right angles to each other, and when the joint members are placed against the jaws they will be forced into the proper relation to form a perfect miter joint. The pivotal mounting of the back jaws permits them to automatically accommodate. themselves to the back edges of the joint members while the front jaws have two joints of'support and consequently will be always.

maintained in the proper relation. It will also'be notedthat: the pivots 27 of the back jaws are threaded into the slide 22, as shown in Fig. 6, and the jaws will be frictionall held intheir pivotal adjustments.

' Having thus described the invention, I claim: p
